Detailed Description
■ ApplicationUsually matching with display instrument, memorizing meter, electronic computer . Directly measure hydrocarbons which may cause explode 0 ~ 500 ℃ about liquid, steam,gas and surface temperature of solid medium at the production site .■ Characteristics● Pressure spring type temperature sensing element, good vibration resistance performance;● large measuring range;● without payment of compensation wire, cost savings;● imported film resistor, reliable and stable performance■ PrincipleExplosion-proof thermal resistance using gap explosion-proof junction box and other components of the design principles, with sufficient strength, all can produce a spark, arc and dangerous temperature components are sealed in the junction box cavity, when the cavity when the explosion occurred, can pass through the gap of joint surface quenching and cooling, the explosion of flame and the temperature sensor is not to outside of the cavity, thus the temperature.■ Main technical parametersExecutive standard ● productIEC751JB/T86221997JB/T96231997JB/T5518-91■ Cold insulation resistanceExplosion-proof thermal resistance is 15 ~ at ambient temperature of 35 ℃, relative humidity of not more than 80%, the test voltage is 10 ~ 100V (DC) insulation resistance than 100M Ω.M between the electrode and the outer tube■ Temperature range and tolerance● temperature range and tolerance■ Selection guidelines1) modelDivision No. 2)3) explosion-proof rating4) accuracy class5) fixed form6) protection tube material7) length or depth of insertionCases of patients with A: explosion-proof thermal resistance, Pt100, fixed thread M27 × 2, explosion-proof grade D to BT4 grade II, protecting tube 316, insert depth 300mm. HR-WZP-240, Pt100, L=450 * 300, D Ⅱ BT4 temperature transmitter 0.5, protecting tube 316, thread M27 * 2.
